bottle feeding a tabby kitten Caring for newborn kittens is an equally exciting and rewarding experience. If something happens to the mother cat or they abandon their kittens, you may need to start hand-rearing them. This can be a time-consuming task, as kittens require milk through all hours of the day and night. A lot of effort and dedication goes into successfully hand-rearing kittens, and since they are so small and fragile, they may not always make it. Bottle feeding is the most important part of successfully hand-rearing kittens till their weaning stage. This article will provide you with tips and tricks and plenty of information when it comes to bottle-feeding and caring for young kittens.

When Should You Hand Raise Kittens?

It is only necessary to bottle feed or hand raise kittens if the following situations were to occur:
  • The mother cat has abandoned their kittens
  • The mother’s milk supply is low
  • The kitten has a medical condition
  • The mother develops a medical condition or passes away
  • The kitten has been rejected from the litter
  • The mother cat shows aggression towards her kittens
  • The kitten requires special veterinary treatment
  • A large litter
  • Note: If you find feral kittens that seem to be abandoned, it is best to wait a few hours to check if the mother comes back to nurse them. The mother cat will venture away from her kittens to find additional food and water for herself, so her kittens will be left alone. Check if they are plump and warm or call the right authorities to help capture and treat the mother and kittens.

How Do You Bottle Feed Kittens?

Bottle/Syringe Feeding

There is no skill required to successfully bottle-feed kittens, you will just need to have the determination and time to care for a demanding creature. This means sacrificing sleep and other duties around the house, to ensure that the kitten’s needs are met.

  • The kittens must be warm before feeding, otherwise, they cannot digest their milk properly. If their body temperature drops to an abnormally low temperature, their metabolism slows down which can have risky side effects.
  • A bottle and teat designed for kittens or puppies are the most common option when it comes to bottle-feeding kittens. Keep track of how much milk you are feeding the kitten. This will ensure that each kitten is receiving enough nutrition daily. You can also use a squirrel teat that has been designed for abandoned baby squirrels. It is best to stock up on bottles and teats in bulk, as you will not have much time to wash and dry each bottle in between feedings.
  • Once the formula is ready, the kitten should be placed on their stomach which is a more natural nursing position. Never place your kitten on their back, as they can aspirate and choke on the milk.
  • Lift the kitten’s chin with one hand and hold the teat near their lips to encourage them to latch onto the teat. The kitten’s tongue should form a V-shape to facilitate suckling. Monitor their head movements so that you can determine if they are swallowing the milk.
Bottles are less messy than a syringe or tube feeding, so there should be less discharge from the bottle and mouth when they are feeding, in comparison to tube or syringe feeding.

Heating Requirements

The formula should be heated by placing the container in a sink or bowl filled with hot water. The formula should be warmed before feeding it to the kittens, as kittens will typically refuse cold formula. Keep in mind that the mother’s milk is naturally warm, so your kitten will expect the milk replacement to be the same temperature. Test a few drops of the formula on your wrist to ensure that the temperature is correct. The drops should be warm and comfortable on your wrist, without being too hot or cool.

6 Tips for Safely Bottle-Feeding Kittens

  • The kitten should lay on its belly with its legs comfortably splayed out. Avoid placing the kitten on its side or back during feeding as this puts your kitten at risk. By laying on their belly, your kitten is automatically placed in a natural nursing position that is safe for them.
  • Keep the kitten warm before feeding so that they can digest the milk replacement at a natural rate. You do not want to overheat them, but rather provide a heating source that replicates their mother’s body heat.
  • Keep a journal or digital copy of the feeding schedule so that you can monitor how much formula you are feeding the kitten. It may also be a good idea to set alarms so that you can determine when the next feeding should be.
  • Prepare the formula in advance so that you do not accidentally rush and miss a step during the process. Your kitten relies on this formula for its health and vitality, so care should be taken when preparing the formula.
  • Care for the kitten after feeding. They will feel tired and sleep, so keep them warm and protected. If you only have one kitten, use a rolled-up blanket or plush toy to provide them with some social companionship. Kittens feel better when they are huddled together, and this also keeps them comfortable.
  • Invert the bottle so that the kitten does not suck in air. Take into account the placement of the mother’s nipples during feeding time, as it is likely that their head is slightly tilted.

Milk Replacement Recipe for Kittens

A homemade kitten milk replacement should only be used for a maximum of 24-hours until you can get a high-quality milk replacement powder from your local veterinarian shop. Petlac Kitten Milk Replacement Powder is a good option for kittens. Not only is it easy for kittens to digest, but it is easy for you to prepare. Mix one tablespoon of the powder with two tablespoons of warm water. This will make approximately 3 tablespoons (1,18 ounces) which can last a small kitten one day. It is best to use boiled water that has been cooled, to keep the formula sterile.

How Much Should You Feed Kittens?

Young kittens should be fed two tablespoons (1 ounce) of milk replacer per day if they weigh between 3 to 4 ounces within 24 hours. Avoid overfeeding the kitten as it can cause them to become bloated, gassy, and uncomfortable. A feeding guideline should be on the back of the milk replacement formulas packaging which will give you a general indication of how much the kitten should eat per its body weight. It is recommended to weigh the kitten every three days so that you can determine how much formula to feed them. This will also give you an indication as to how much they are growing so that you can accommodate their feeding requirements.

How Often Must You Feed Kittens?

Kittens that are less than two weeks old should be fed every 2 to 3 hours. This includes during the night. You will have to get up during the night and sacrifice sleep to feed your kitten, however, with the advice from your kitten’s veterinarian, you can feed kittens less at night if they have been at an ideal weight. Kittens between two to four weeks of age should be fed every 3 to 4 hours on average. They will get used to reduced nightly feedings but should still be fed according to a 24-hour schedule. After four weeks of age, kittens should be fed every 4 to 5 hours. They may begin to sleep better during the night without crying for milk every couple of hours. Once the kitten reaches eight weeks of age, they should be slowly weaned from the milk replacement and introduced to a wet food diet suitable for kittens.

Final Thoughts

Raising kittens is often a delicate task that requires help and encouragement from others. It is recommended to always have a backup plan in the case that you are not with the kitten for a prolonged period. The person helping you will then be able to step in and bottle feed your kitten while ensuring that they are warm and comforted. Always work closely with a veterinarian or professional when hand-rearing kittens, as they know what’s best.
